Such studies, however, can only measure the effects of acute exposure to air pollution on premature deaths and/or morbidity. As these studies cannot capture chronic effects of exposure to air pollution, their estimates should be considered as lower bound estimates of reduction of premature deaths due to drop in air pollution level. A large number of studies came out in last few years using the methodology, mostly from developed countries7. Almost all of them found strong positive correlation between level of air pollution and mortality/morbidity rates.
